CHICAGO, rumors, ASSIGNOR 'IO sAGEa META-L WEATHERSTRIP (30., OF CHICAGO, ILLINOIS, A CQBPORATION OF ILLINOIS METAL wEATnnns'rRIr This invention relates in general to metal parting beads andhas more particular reference to metal tubular parting beads which are adapted to act as Weatherstripping in connection with metal sliding members provided on window sash.

A principal object of the 'presentinvention .is the provision of an all-metal tubular partingbead formed to provide an interlocking slide and weather seal in cooperative relation with sliding membersprovided on wooden window sash. r 7

Another important object of this invention is the provision of an all-metal tubular parting bead so formed that it may be readilyinstalled in the usual parting bead recess formed in wooden window frames, and there secured by clamping the same against the sides and bottom thereof to form a weather seal between the side walls of the parting bead and the recess of the window frame. i

A further object of the invention is to provide the sliding members thereof, which slidably engage each other, with rounded portions to avoid any scraping action or undue friction in opening or closing the window."

A further object of the invention is the provision of an all-metal tubular parting head forming an interlocking slide and y I bodiment thereof.

Referring to the drawings: Figure 1 is a vertical sectional view through a window frame and the window sash installed therein and includes'the ini stallation of the combined parting bead and Weatherstrip containing the improvements as embodied in my invention; Y Fig.2 is a section taken on the line 2-2 of Fig. l;

Application filed March 2,

1929. Serial No. 344,069.

Fig. 5 is an enlarged detailed view of the back portion of the parting bead and shows the manner in which it is held against the side walls of the recess of a window frame, as by means of a screw which also clamps the head against the bottom of the recess, substantially as indicated in Figs. 2 and 3..

I For the purpose of more clearly illustrating my invention, I have shown on the drawings a portion of a window frame or casing together with the window sash as installed therein on eitherside of the parting bead containing the improvements as embodied in my invention, indicated generally by the reference character 11. Particular description of the window frame 'or window sash is unnecessary to an understandingof the present invention except to state, however, that the window frame is provided with its usual parting bead recess 12, and the window sash is provided withmetal sliding members or rails 13.

Referring to the several views, and particularly to Fig. 4:, it will be seen that my improved combined parting bead and weather? strip are formed from a comparatively nar row strip of sheet metal 14 into a tubular shape, indicated generally by the reference character 1.5.

In the present preferred form of my invention, as formed from the metal strip 14 and of which a portion thereof is formed to comprise a front wall 16 which is curved inwardly or toward the back of the bead throughout its entire length to form a shallow longitudinal recess, and midway thereof, arelocated a series of spaced holes 17 which are adapted to receive screws 18 which bead 15 in place.

clamp the parting From each. side of thefront wall 16 the metal strip 14 is bent back and then folded back upon itself until it comes in contact with the back of the front wall, as at 19, to form two lateral walls 21, similar and pal-al lel with each other substantially at right angles to a longitudinal plane parallel with the front wall 16. In forming the first fold, as at 22, rounded edges are produced to avoid any scraping or undue friction between the engaging sliding members or rails 13, as provided on the window sash 23. It may be stated here that the front wall is recessed for two reasons; first to giveit resiliency, and second, to provide a means by which the screw heads will not be protruding beyond the highest part of the front wall.

From the point 19, the remaining portions of the strip 14 are each bent back in a return bend to form two similar parallel walls 24a,

equally spaced from and parallel with thewalls 21, and the remaining portions of strip 14 are bent outwardly at approximately an angle of 45 degrees, as at 25, and then bent back again to form two similar parallel walls 26, substantially in line and in parallel relation with the walls 21, and the still remaining portions of the strip 14 are each bent inward ly or toward each other a like distance to form a right angle with each of the walls 26 and so that the opposite edges 27 of the strip 14: will be parallel to each other and in line and in suitable spaced relation from each other to form the back walls 28 of the parting bead 15.

On inserting the parting bead 15 into the recess 12, it is pinched together, as indicated in Fig. 5 by the dotted lines 26, and when in place, released, whereby, owing to the resiliency of the front wall 16, it springs back to its normal condition clamping itself automatically against the side walls 29 of the recess 12. As a further means of securely clamping the walls 26 against the walls 29, a screw or screws 18 are provided and on being inserted through the holes 17 and between the edges 27, and screwed in the window frame as indicated in Figs. 2, 3 and 5, clamp both of the walls 26 tightly against the walls 29 and also clamp the back walls 28 securely against the bottom of the recess 12.

Referring to Figs. 2 and 3, it willbe seen that the spaced relation of the walls21 and 24 is such that the sliding rails 31 of the member 13 engage the surfaces of both the walls 21 and 24. However, the fit between the parts is not so close as to prevent easy move ment up and down of the windows but is sufficiently close to form substantially a perfect weather seal between the parts.

It is thought that the invention and many of its attendant advantages will be understood from the foregoing description, and it will be apparent that various changes may be made in the form, construction and arrangement of the parts without departing from the spirit and scope of the invention or sacrificing all of its material advantages, the form hereinbefore described being merely a preferred embodiment thereof. a

I claim:

1. A Weatherstripping comprising a metal member of boXlike shape adapted to replace the parting strip of a window frame with its edges arranged in the parting strip groove, and a metal strip attachable to a window sash in interlocking engagement with the parting strip replacing member.

2. A Weatherstripping comprising a metal member of boxlike shape adapted to replace the parting strip of a window frame, the side walls of said boxlike shape being reversely folded to provide angular channels extending the length of the member, and an angle part attachable to the window sash and slidably interlocked in a said channel.

3. A Weatherstripping comprising a window frame strip bent to boXlike form with its edges facing toward each other at the base of said boxlike form, and window sash strips interlockingly engaging said window frame strip.

1. A Weatherstripping comprising a window frame strip bent to boxlike form with its edges facing toward each other at the base of said boXlike form, and window sash strips interlockingly engaging said window frame strip, and fastening members passing through the center of said window frame strip and between said edges. 1

5. A Weatherstripping comprising a window frame strip folded adjacent its longitudinal center to provide parallelly arranged loops and there beyond to provide side walls giving to the whole a boxlike construction, and angle members attachable to the window sash in slidable interlocking engagement with said loops. 7 p

6. A Weatherstripping comprising a metal member adapted to replace the parting strip of a window frame and having a boxlike section for insertion into the window frame, said metal member having outer wall sections parallel to but spaced inwardly of the outer wall sections of the section adapted to fit into the window frame and having also return bends from the edges of said outer wall sections, and angle members attachable to the window sashes and engaging between said outer wall sections and said return bends.

7. A Weatherstrippingcomprising a metal member adapted to replace the parting strip of a window frame, and having a box-like section for insertion into the window frame, outer wall sections parallel to, and spaced inwardly from the sides of said box-like section, and flanges extending from the outer edges of said outer wall sections inwardly toward said box-like sections in parallelism, and angle members attachable to the window sashes and engaging between said outer wall sections and said flanges.
